Hairpins are inversed by double clicking on palette

Last Nigthly, December 16 (abbf2c8) / Windows7

1. "My First Score"
2. Fill some notes in the two first measures
3. Select a note -> open Lines Palette -> double click on the crescendo sign

Expected result: a crescendo

Actuel result: a decrescendo

Same inversion, when double clicking on the decrescendo sign.

This issue appeared today on this last Nightly at the implementation of this new and useful function :)
